Abstract

A simple dual-band Fabry-Perot resonator (FPR) antenna is presented in this paper. The dual-band wave is excited by a rectangular patch and a single coaxial. The FPR antenna consists of a partially reflective surface (PRS) and metal ground plane. The PRS is formed by rhombus slot frequency selective surface (FSS) and square metal patch FSS. In addition, the upper surface of the metal ground plane is also the FSS of square metal patch. The profile of the prototype has reduced to nearly one-sixth of the working wavelength. The peak gains of this antenna in the band of 8.5GHz and 11.5GHz have reached 17.6dBi and 16.3dBi respectively and the reflection coefficients in both band are all less than −10dB.
